In view of the promising antimalarial activity of fosmidomycin or its N-acetyl homologue FR900098, the objective of this work was to investigate the influence of aromatic substituents in the alpha-position of the phosphonate moiety. The envisaged analogues were prepared using a linear route involving a 3-aryl-3-phosphoryl propanal intermediate. The activities of all compounds were evaluated on Eschericia
鉴于磷霉素或其N-乙酰基同系物FR900098的有希望的抗疟活性,这项工作的目的是研究膦酸酯部分α-位上芳族取代基的影响。所设想的类似物是使用涉及3-芳基-3-磷酰基丙醛中间体的线性路线制备的。在大肠杆菌1-脱氧-d-木酮糖5-磷酸还原异构酶和两种恶性疟原虫菌株上评估了所有化合物的活性。与磷霉素相比,几种类似物显示出对恶性疟原虫菌株增强的活性。在磷霉素的α-位具有3,4-二氯苯基取代的化合物1e成为该系列最有效的类似物。抑制恶性疟原虫生长的效力是FR900098的三倍,
